To all whom it may concern I Be it knownthat L'ALVIN G. fMcCoRn, acitizen of the United States, residing at Chicago, in the county of Cookand State of Illinois, have invented 'certain'new and usefulImprovements in Pressed-Steel Journal- Boxes; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as'will enable others skilled in the art to which it'appertains to make and use the same.

Particularly, my invention'has for its obj'ect' to provide an improvedall pressed steel journal box in which the box proper may be stampedor'pressed from a single piece of sheet steel, and to such ends,generally stated, the invention consists of the novel construction andcombination of parts hereinafter described and defined the claims. Theinvention involves two main novel features and'certain other importantminor features.

The first of the said main. novel features consists in forming thecellar and top ofthe box from a single piece of sheet steel, byproviding integral extensions from thesideforming portions of the sheetand bending these, one over the other, and overlapping the same to formthe top or roof of the box. This construction not only reduces thenumber of parts of the boxbut provides a very strong top in which theoverlapped inner and outer top forming plates will be held together bythe weight or pressure on the top of the box, and thereby very greatlyreducing the necessity of welding or otherwise connecting the said topplates. 7

The second principal novel feature consists in forming the pressed steelcellar of the box with an integral inwardly-pressed corrugation or ribthat constitutes the inside dust guard wall. This dust guardwall may beproduced as a part of'the operationrequired to press the sheet into theform of a cellar, and hence, reduces the cost, eliminates the necessityfor welding and provides an oiltight joint whichwill prevent leakage ofoil 'fIOITL'thB cellar into the dust guard seat.

In the accompanying drawings which illustrate the invention, likecharacters indicatelike parts throughout the several views.

Application filed. February 8, 1915. Serial No. 6,789;

First note the construction illustrated in Flgs. 1 to 6, inclusive' Fromthe blank stamped as shown in Fig. 1, the cellaror body 1 of the box ispressed into the form shown in Figs. 2 to 6, inclusive. Here it may benoted that the bending'lines, of the blank, Fig. 1, are indicated bydottedlines marked y, yfiyflg and y. l The side forming portions of thebox are between the bending llnes 2 and 3 The plate 2 is bent ion lineand constitutes the inner top formng plate, and it is bent on the line 23 to form a depending flange 2 that engages against the inner uppersurface of one side of the cellar. By bending on the inner line y, theouter top forming plate 3 is extended over the entire top of the box andis brought down against and overlapped with the said inner top plate 2;and by bending on the 'lines l depending flanges are provided whichoverlap with the outer upper surfaces of the sides of the box. Thecellar 1 is provided with depressed bosses 4: that flatten the bottom"thereof for engagement with the lower archbar, and in approximately thesame transverse vertical plane, the sideforming portions of the cellarare provided with inwardly-pressed bosses or bulges 5 that afiord centerbrassestops. On a proper transverse line between the bosses t and theinner end of the box, the blank is formed with a deeply pressed rib orcorrugation 6 that extends across the bottom and well up theside-forming portions of the sheet, and which, when the cellar ispressed into shape, has a segmental form, as best shown in Fig. 6, andconstitutes the inside dust guard wall of the box. By bending the narrowportions I of the blank, 1, on the lines g g upon themselves, and thencedownward against the sides of the box, ,asbe'st shown'in Fig. 3, the boxis provided with outwardly pro ecting lugs 7, that are perforated at8,so as to pass the archbar bolts. At its transversely central outer endportion, the outer top I forming plate 3 has an integral upwardlypressed hollow lid hinge lug 9 that may be located in an upwardly bulgedportion on a the said plate, but in any event, properly positioned inrespect to the integral: inside dust guard wall 6,'softhat the dustguard '(not shown) will be properly positioned between the same and theinner end flange 12 of the cellar. The depending flanges onthe topforming plates 2 and 3, which overlap the sides and inner end ofthecellar, would usually be connected by spot-welding, and if lugsdesired,said plates 2 and 3 may also be spotwelded. Approximately inline with the arch bolt lugs 7 the top plate 3 is formed with one ormore raised corrugations 13 which, increase thestrength of said plateand afford a suitable top arch bar seat.

Theconstruction illustrated in Figs. 7 to 11, inclusive, is very muchlike that llustrated in Figs. 1 to 6, inclusive, but differs therefromin that both of the top-forming plates 2 and 3 are directly united tothe cellar forming portion of the blank, and the reduced portion 1 1,which forms the top arch bar seat or seating yoke, is projected entirelyfrom one side of the outer topforming plate 3. In forming the boxfromthe blank 7, the outer plate 3 is folded on top of the inner plate 2, asnoted ,in the description of the formation of the box from the blank 1,and thereafter, the arch bar seating yoke 14: is bent on the linesmarked m M, to thereby cause the said yoke to project and serve as. archbar lugs, and which are provided with suitable bolt holes 15. Otherwisethan noted, the box shown in Figs. 8 to 11, may be assumed to beidentical with that shown in Figs. 2 to 6,

inclusive, although the lid hinge lug 9 which is pressed from the othertop-forming plate 3, as illustrated,'diflers from the lug 9 in theparticulars not necessary for the purposes of this case to consider.
